HOHTICULTURAL SCALDING APPARATUS Filed Dec. 2?, 192's 2 Sheets-Sheet 2 Patented Jan. 26, 1932 UNITED STATES ALEXANDRE VEDRINSKY, OIE PARIS, FRANCE HORTIGULTUBAL SCALIJII LNG APPARATUS Application filed December 27, 1928, Serial No. 328,817, and in France J'anuaryli, 1928.

My invention relates to a portable apparatus tor heating liquids and particularly for scalding vines, trees, and other plants, which operation is known, per se, and is destined to destroy ous larvae.

it is the object of my invention to provide a pouring apparatus adapted to be easily certain insects,worms and injuricarried and manipulated by hand, and my apparatus is characterized by the fact that it is provided, on the one hand, with suitable heating organ, of the compressed gas, gasoline, kerosene, alcohol, or analogous type,

and on the other hand, with one or more tubular coils communicating with each other, adapted to be heated by the heating organ, and connected on the one hand through an in let tube with a flexible cold liquid feeding tubing, and on the other hand with a suitable JOi'll'lIl or an such as a tube or s out for example.

By means of this disposition of parts, the cold liquid runs out either under pressure or by gravity through the flexible feeding tube and then through the inlet tube, circulating ment of the flow of the liquid, the said cock being adapted to be operated by hand or preferably combined with a suitable control organ such as a comblnation of levers'adapted to allow manipulation of the sald cock with one .4; of the lingers or the thumb, for example, the

hand of the operator grasping the handle of the apparatus and a spring being adapted to tend to return the cock to a position of minimum flow. My device, it is to be understood,

- is also provided with a stop cock for shutting oil completely the flow of liquid independently of the aforementioned cock and rigidly disposed on the tank containing the cold liquid.

My invention will be more readily understood with reference to the accompanying drawings illustrating a number of embodiments of my invention by way of example, and in whichi I Fig. 1 is an elevational view of my apparatus; a 5.3 F Fig. 2 is a middle vertical section through Fig. 3 is a detail in plan of the coils of my apparatus;

FFig. 4 is a section along the line 4-l of co Fig. 5 is a detail view of a modified form of coil;

Fig. 6 is another detail view of a second modified form of coil;

Fig. 7 and Fig. 8 are respectively detail views illustrating the formation of the coil of Fig. 6;

Fig. 9 is a section along the line 99 of Fig. 8; and p Fig. 10 is a detail of another modified form of coil.

Referring to the drawings more in detail, the heater a of any suitable form known in the art, is provided with three burners 6, b 6 (Figs. 1 to 4;) which are regulated with control valves 0, 0 c as well as two lugs a supporting a handle a Around the upper part a of the burner a are fixed movably in a suitable manner, a dome (Z of perforate form so and an exterior housing 6 rigidly connected together at their bases and insulated one from the other in the body thereof by a chamber of heat-insulating air. The exterior housing 6 is closed by a perforate top 6 for allowing the gases of combustion to escape. A double coil composed of a single tube f is disposed in the dome (Z and is made rigid therewith by suitable means not illustrated, such as by soldering or cramping or like means known in the art. Tube f, starting from an inlet portion f is laid down in a series of superposed coils having the form shown in Fig. 4 and limiting a chamber 9 heated by burner b. When, in the course of the construction of chamber 9, tube f reaches the top of the latter, a loop of the type shown in the center of Fig. 3 is made and a series of coils similar inform to those limitingchamber g are wound to form a chamber g similar windings f f and by burners b and while form a discharge portion 7.

be heated by burners band 5 while moving upward from f to the topof the coil through descending from the top of the coil to outlet f through windings f, Itis'to be noted that portions 7, f of the coil are simultaneously heated on both sides by burners I); b and b b 1 The hereinabove 1' described method of winding tube f insures a maximum of heating surface for a'given volume.

a The inlet tubing f isprovided with a cock h-for regulating and having a constant inini- 1 mum flow and rigid with a toothed wheel It engaging with a toothed sector 2. The said sector is pivoted on a stud 2' rigid with the lug a and carries a forked arm 2' The said arm fits beneath a push buttom j over a rod j slidably mounted in the handle (1 A spring in bearing on the handle a and beneath the forked arm z' pushes the said arm into raised position and hence moves the cock into a position of minimum flow. A flexible tube 05 connected to the tube f serving as an inlet connects with the stop cock of the tank con taining the cold liquid (not shown) Referring to Fig. 5, the coil is co'nstitutec by rolling a tube in the form of a dome, first from the bottom to the top, this part being represented by the coil 7" on theinside, and then from the top to} the bottom in a'winding i disposed'aroun'd said first interior coil, the feedingof the liquid taking place'through one of the extremities such-"as f and the drawing off taking'place through theother extremity of the tube i orviceversaJ The coil illustrated "n Figs.6"to 9 is" like wise composed of a single tube and is provided with an interior windingf and an extGIlOI'WlIlCllng f 1n the form of a dome; In

" this mbodiment the winding is produced in a manner which willnow be described.

The tube is first folded over on itself as in Fig. 7 formingfa U-bend f and two arms f and 7 The U-bend f forming the base of i l the interior winding 1 (Figs. 8 and 9), the' two arms 7" and f of the tube are wound together up to the top of the dome and then caused to descend from top to bottom in a way. to establish the exterior winding f r The two extremities f and f of the tube form,

irrespectively either inlet or outlet for th e" liquid. p

In the embodiment of. Fig. 10, the tube forms successively three substantially conical coils f", f, 7? coupled together and inter- Likewise the accessory forms and arrangements of the-various-members'o-f the devlces disclosed, the dimensions, the constituent materials, the details and the means for c arrying the invention into practice may be Varied without departing f'rom the'spirit of the inventionas comprehended Within the scope of the appended claims. i

It is likewise to be understood that the par tic'ular forms of coils described and hereinafter claimed may be utilized in connection with the, heating of any liquids and all ap propriate uses and still come within the scope of the appended claims. Having described my invention what I claim as new and desire to secure by Letters Patent of the United States of America is :f
